Title: Depression of carbonaceous material in flotation
IPC: B03D1/008
Filed: 1938-12-19
Abstract: 508,929. Concentrating ores. AMERICAN CYANAMID CO. Dec. 19, 1938, No. 36959. Convention date, Feb. 1. [Class 82 (ii)] In the concentration by froth flotation of carbonaceous precious metal ores, a dextrine, preferably yellow corn dextrine, is added to the pulp to depress the carbonaceous material. The dextrine may be used in the rougher flotation or, if desired, only in the cleaning of the rougher concentrate. A carbonaceous pyritic gold ore may be ground with yellow corn dextrine, conditioned with soda ash and copper sulphate and floated with pine oil, secondary butyl xanthate and a mixture of sodium diethyl and disecondarybutyl dithiophosphates. In another example, a similar ore is first floated without the use of dextrine and the concentrate either cleaned simply with addition of dextrine or conditioned with dextrine and floated with copper sulphate, more dextrine and secondary butyl xanthate. Alternatively, all of the dextrine may be added in the conditioning step. The cleaned concentrate may be recleaned with further additions of dextrine, copper sulphate and butyl xanthate. A copper-gold ore containing graphite may be conditioned with dextrine, secondary butyl xanthate and a mixture of sodium diethyl and disecondarybutyl dithiophosphates and then floated with addition of dicresyldithiophosphate and a synthetic frother consisting of a mixture of higher aliphatic alcohols. The flotation of a carbonaceous silver ore is also described.

Abstract: 959,708. Slip couplings. MAYBACHMOTORENBAU G.m.b.H. Oct. 19, 1961 [Oct. 20, 1960], No. 37612/61. Heading F2C. In a friction clutch between a drum 24 on a shaft 11 of an internal-combustion engine and a shaft 20 of a combined starter and dynamo, providing low torque transmission and overload slip for normal engine-to-dynamo drive and a high torque transmission when using the dynamo as engine starter, ring members 39, 33, keyed fast and for limited rotation respectively on the shaft 20 have facial cams 38, 37, which, when using the dynamo as engine starter, increase the clutch pressure by causing axial displacement of clutch plates 26, 30, against a balancing thrust of Belleville springs 49 but, when the engine drives the dynamo, cause retraction of the cammed ring 33 so that clutch pressure is balanced between the Belleville springs and a coil spring 42, providing a low clutch torque, permitting overload slip for dynamo protection. The clutch plates are arranged in two sets, one 26, a large set directly connects the clutch members 24, 20, and another small set 30, connects the member 24 to the cam ring 33. The small set 30 provides a frictional resistance to the relative turning of the cam ring 33. Oilways 51, 52 and 53 provide lubrication.

Title: Improvements in apparatus for reproducing signals transversely recorded on magnetic tape

IPC: G11B15/14
Filed: 1960-11-03
Abstract: 989,482. Magnetic tape recorders. RANKBUSH MURPHY Ltd. Nov. 2, 1961 [Nov. 3, 1960], No. 37784/60. Heading G5R. [Also in Division H3] In reproducing signals recorded transversely on magnetic tape by transducer heads rendered operative in turn the signals are gated to a common output through delay lines whose delay is retroactively controlled from a phase detector so that a change-over of transducer head is effected without altering the phase of the reproduced frequency modulated carrier signal. In Fig. 2, gated outputs of heads 1, 2, 3, 4 operative in sequence are applied through delay lines 23, 24 to phase detectors 28, 29 whose outputs vary the delay of lines 23, 24 so that the incoming delayed output from a head is brought into phase agreement with the operative delayed output before the change-over. In a modification, only one delay line is variable, and one phase detector used, but alternately its output is blocked from the variable delay line so that the variable delay line returns to its initial delay (equal to that of the fixed delay line) alternatingly. In this case the gating may be controlled by signals developed by the four heads, as in Specification 902,771. The phase comparator may comprise two tapped delay lines, one producing two trains of time displaced pulses with which are additionally and subtractively combined a pulse train of intermediate timing from the other delay line to develop a composite positive and negative going pulse train whose average value varies with the relative delay between the two delay line outputs and, integrated, produces a D.C. control voltage of variable magnitude and polarity correcting the delay in one line.

Title: Error detector for pseudo-random sequence of digits

Filed: 1974-08-30
Abstract: 1461183 Digital transmission systems; testing NORTHERN ELECTRIC CO Ltd 30 Aug 1974 [30 Aug 1973] 38112/74 Heading H4P In an error detector 30 for detecting errors in a digital transmission system 20 including a pseudo-random sequence generator 10 for transmitting a pseudo-random sequence of digits, a comparator 40 is responsive to the sequence of digits for generating a replicated sequence of digits including a pattern of wrong digits in response to a single wrong digit in the pseudo random sequence at an output of 42 which it compares at 43 with those of the pseudo-random sequence from 10, 20 to derive indicated error digits when anticoincidence is detected between the sequences. In addition a corrector 50 is responsive to true error digits from 43 for generating replicated error digits in a pattern corresponding to the pattern of wrong digits at an output from 53 and compares the indicated error digits from 43 with the replicated error digits from 53 at 51 to derive the true error digits at an output from 51 when anticoincidence is detected between the indicated and replicated error digits.  As shown the pseudo-random sequence generator 10, the comparator 40 and the corrector 50 include shift registers 11, 41 and 52 and modulo 2 adders or exclusive OR gates 13, 42, 43, 51 and 53. A clock recovery circuit 31 drives the shift register 41 so as to generate a replicated sequence of digits at the output of gate 42. Provided the comparator 40 remains in synchronization with the generator 10 a single error digit from the digital system 20 results in three indicated error digits '1' at the output of gate 43. The shift register 52 of the corrector 50 functions to cancel the additional '1's, resulting from receipt of the initial error digit, in gate 51 so that the output of gate 51 provides only one true error indication signal. If synchronization is lost, initially a number of errors will be recorded at the output of the comparator 40 until resynchronization between it and the generator 10 is automatically reestablished. However, once synchronization is re-established in the comparator 40 the corrector 50 will continue to circulate a pseudorandom sequence of logic '1's and '0's rather than all logic '0's even though logic '0's are being received from gate 43 indicating an error free signal. This results in a false error count at the output of the gate 51. The output of logic '1's from gate 51 is now greater than that from the output of gate 43 and these outputs are fed to a counter 60 the output of which indicates the number of times synchronization is lost and resets the shift register 52 of the corrector 50.
